A Transformative Math Workshop: Our Summer [Co]lab
11600 Welch Rd, Dallas, Texas 75229
June 22-24, 2026
What is the [Co]lab?
The [Co]lab is a 3-day immersive workshop designed to help K-8 educators, math coaches, and school leaders shift to a philosophical understanding and pedagogy that is learning-centered and builds deep understanding of math as a discipline. The [Co]lab is our flagship professional learning experience and serves as a starting point for many educators.
What will I learn at the [Co]lab?
Throughout the three days of the [Co]lab, we'll explore the high-leverage concepts of our Generative Framework and understand the ideas that connect arithmetic to algebra. We'll also overview the practices that anchor a Number Lab Math Block, highlight important models that support deep understanding, and learn more about what contributes to positive classroom culture and productive discourse.
Why should my colleagues and I attend the [Co]lab?
The [Co]lab is a disruption of the traditional, narrow practices and norms of K-12 math education. By engaging in this workshop, you will leave with a newfound love and appreciation for math, an understanding of the importance of a conceptual focus that nurtures reasoning, and clarity on how to shift your practices to support a classroom culture conducive to collaboration, discussion, and critical learning skills. The best way to attend the [Co]lab is with colleagues, as this will be a transformative experience for you as a mathematician and as a teacher. You’ll want to share it with peers so you can support one another in shifting to practices in your classrooms that empower children to reason and to engage in argument in a way that honors the thinking of others, while producing a new and deeper understanding of the discipline.
The [Co]lab will provide a unique, collaborative, hands-on experience for you and your colleagues and you’ll want to return each summer.

The math content that we focus on in the [Co]lab falls in the range of kindergarten through Algebra, though we welcome participants in grade levels beyond Algebra, as we have had teachers find that the content and pedagogy can be transferred to their teaching contexts.
